【発明の詳細な説明】 本発明はグラビア印刷版の製造方法に関する。[Detailed description of the invention] The present invention relates to a method for manufacturing a gravure printing plate.

、印刷後繰返し注文がある仕事の場合保管しておく必要
があり、このための保管スペース、保管本数は大規模な
ものとなる。Conventionally, gravure printing uses intaglio cylinders with iron rolls as the core material, but intaglio cylinders require a lot of heavy electricity and are very expensive. Furthermore, intaglio cylinders need to be stored in cases where there are repeated orders after printing, which requires a large amount of storage space and a large number of cylinders.
また、保管場所から印刷機械への凹版シリンダの運搬に
手間がかかるという問題もある。Another problem is that it takes time and effort to transport the intaglio cylinders from the storage location to the printing machine.
このような問題を解消するために、金属多重層よりなる
薄膜状のスリーブ版により版材を作ってこれを製版し、

されている。In order to solve this problem, a plate material is made from a thin film-like sleeve plate made of multiple metal layers, and this is used for plate making.
It has been proposed to attach this to the outer peripheral surface of a printing roll only during printing, and to remove it from the printing roll and store it after printing.

ダから引抜くことにより製造されている。The sleeve plate used for such gravure printing plates is formed by plating a single or multilayer metal layer on the surface of an iron core that has been subjected to mold release treatment called a mother cylinder, and after surface polishing, it is plated with a conventional or direct plate. It is manufactured by making a gravure printing cell using an etching method and then pulling it out from a mother cylinder.

に統みとり彫刻むらが発生し易い。It has a surface consisting of a color range of Cr or the like with excellent mold releasability, and the metal layer obtained by plating this surface is in a state where it is easily peeled off by controlling the plating stress. Therefore, during the surface polishing process or the like, the metal layer may shift or bulge partially, which may cause unevenness during plate making. Particularly, when making a plate using an electronic engraving machine that has been put into practical use recently, even a slight local bulge tends to cause the engraving head to subtly consolidate, resulting in uneven engraving.

生じ易くなる。The present inventors have discovered that when a virgin tensile load is applied to a Metsuki sleep plate within a proportional limit and the load is unloaded, the Metsuki sleep plate does not return to its original dimensions and tends to undergo permanent elongation. Due to this phenomenon as well, the matsuki sleep plate on the mother cylinder is easily displaced during the surface polishing process or the like.

的が達成される。According to the present invention, a metal layer is formed on the surface of the mother cylinder which has been subjected to mold release treatment! After forming a sleeve by plating, the sleeve is pulled out from the mother cylinder and inserted into a printing roll having a slightly larger outer diameter than the mother cylinder while being heated with a hot-melt adhesive, thereby printing the sleeve. This goal is achieved by fixing the sleeve to a printing roll and then forming the usual gravure printing cells into a sleeve and making the plate.

is the mother cylinder, which is made of a mold-released iron core. Next, on the surface of this mother cylinder 1, N
A single or multilayer thin layer 2 of Cu, Cu, etc. is formed by plating. This thin layer 2 constitutes a sleeve. This sleeve 2 is then pulled out from above the mother cylinder as shown by the chain line in FIG.

リーブ２の弾性変形特性は安定する。A tensile load is applied to the sleeve 2 in the circumferential direction as necessary, and then the load is removed. Although the tensile load is applied within the elastic limit, the thin layer sleeve 2 formed by plating does not return to its original state even after the tensile load is applied and is unloaded, resulting in permanent elongation. However, once such pretreatment is applied, the new elongation will be proportional to the load below the previously reached tensile load value, and when the load is unloaded, the elongation will be in a similar proportional relationship. Decrease. This relationship is
After that, even if tensile loading and unloading are repeated, the elastic deformation characteristics of the sleeve 2 remain stable.

化し、スリーブ２をロール３の外周面に保持する。The sleeve 2, which has been pretreated as necessary, is fitted onto the outer peripheral surface of the printing roll 3, which has a slightly larger outer diameter than the mother cylinder 1, as shown in FIG. For this purpose,
The sleeve 2 is heated to thermally expand, and a hot melt adhesive is interposed between the outer surface of the printing roll 3 and the sleeve 20. The pot-melt adhesive is first applied to the outer periphery of the roll 3, for example, from above, and then the sleeve 2, whose diameter has been expanded by thermal expansion, is fitted from the upper end of the roll 3 as indicated by the arrow in FIG. After the sleeve 2 has been fitted over the entire length of the roll 3, the hot melt adhesive solidifies and holds the sleeve 2 to the outer circumferential surface of the roll 3.
このようにしてスリーブ２が印刷用ロール３の外周面に

方法によりグラビアセルが形成され、グラビア印刷版が
得られる。After the sleeve 2 is immovably fixed to the outer peripheral surface of the printing roll 3 in this manner, gravure cells are formed on the outer surface of the sleeve 2 by a known method to obtain a gravure printing plate.

れ、良好な印刷を行なうことができる。By holding the sleeve 2 on the roll 3 using a hot melt adhesive, the sleeve will not shift even if the surface of the sleeve 2 is polished, and the doctor pressure and impression cylinder during printing after plate making will be prevented. Even with the strong pressure caused by this, problems such as the sleeve slipping around or floating can be completely prevented, and good printing can be performed.

After surface degreasing and mold release treatment, it was made into an iron core T mother cylinder made of aluminum, and after surface degreasing and mold release treatment, it was heated to about 150 μm in a sulfur amino acid nickel bath.
Ni plating is performed, followed by another 15 plating in a copper sulfate bath.
0μ Cu plating was performed. After plating, the surface of the plated layer was ironed with a T-roller, and the 300 μ thick sleeve was pulled out from the mother cylinder (note that the ironing treatment may be performed immediately after Ni plating). A stress relaxation agent was added to the Ni plating bath as necessary to facilitate mold release. Also, during the ironing process, the mother cylinder was heated as necessary to facilitate removal.
